Transport of topological semimetals

J Hu, SY Xu, N Ni, Z Mao - Annual Review of Materials Research, 2019 - annualreviews.org
Three-dimensional (3D) topological semimetals represent a new class of topological
matters. The study of this family of materials has been at the frontiers of condensed matter …

Electron-phonon hydrodynamics

X Huang, A Lucas - Physical Review B, 2021 - APS
We developed the theory of hydrodynamics of an isotropic Fermi liquid of electrons coupled
to isotropic acoustic phonons, assuming that umklapp processes may be neglected. At low …

Extremely high conductivity observed in the triple point topological metal MoP

N Kumar, Y Sun, M Nicklas, SJ Watzman… - Nature …, 2019 - nature.com
Weyl and Dirac fermions have created much attention in condensed matter physics and
materials science. Recently, several additional distinct types of fermions have been …

Anomalous hydrodynamic transport in interacting noncentrosymmetric metals

R Toshio, K Takasan, N Kawakami - Physical Review Research, 2020 - APS
In highly conductive metals with sufficiently strong momentum-conserving scattering, the
electron momentum is regarded as a long-lived quantity, whose dynamics is described by …

Viscometry of electron fluids from symmetry

CQ Cook, A Lucas - Physical Review Letters, 2021 - APS
When electrons flow as a viscous fluid in anisotropic metals, the reduced symmetry can lead
to exotic viscosity tensors with many additional, nonstandard components. We present a …

Formation of an electron-phonon bifluid in bulk antimony

A Jaoui, A Gourgout, G Seyfarth, A Subedi, T Lorenz… - Physical Review X, 2022 - APS
The flow of charge and entropy in solids usually depends on collisions decaying
quasiparticle momentum. Hydrodynamic corrections can emerge, however, if most collisions …

Evidence of a coupled electron-phonon liquid in NbGe2

HY Yang, X Yao, V Plisson, S Mozaffari… - Nature …, 2021 - nature.com
Whereas electron-phonon scattering relaxes the electron's momentum in metals, a perpetual
exchange of momentum between phonons and electrons may conserve total momentum …

Hydrodynamics with triangular point group

AJ Friedman, CQ Cook, A Lucas - SciPost Physics, 2023 - scipost.org
When continuous rotational invariance of a two-dimensional fluid is broken to the discrete,
dihedral subgroup $ D_6 $-the point group of an equilateral triangle-the resulting …

Optical signatures of shear collective modes in strongly interacting Fermi liquids

D Valentinis - Physical Review Research, 2021 - APS
The concept of Fermi liquid lays a solid cornerstone to the understanding of electronic
correlations in quantum matter. This ordered many-body state rigorously organizes electrons …

Dynamo effect and turbulence in hydrodynamic Weyl metals

V Galitski, M Kargarian, S Syzranov - Physical review letters, 2018 - APS
The dynamo effect is a class of macroscopic phenomena responsible for generating and
maintaining magnetic fields in astrophysical bodies. It hinges on the hydrodynamic three …
